The month long sit-in of Sudan’s revolutionaries has carved a small district out of the centre of Khartoum, with its barricades, tents, art corner, transport system bringing fresh cohorts, and sound system.
The Youth of the Tunnel beating the rails of a railway bridge above and irons sheets below have become a sort of metronome for the revolution.
They refuse to leave until the armed forces hand power to a civilian government and are prepared to endure oven temperatures during Ramadan to keep the pressure up.
But it is the quieter sounds and backstage meetings that also matter.
Crushing the revolution
Last week, a joint Saudi-Emirati delegation was reported to have arrived in Khartoum for meetings with members of Sudan's transitional military council, although the names of members of the delegation have not been officially made public.
In Yemen, Egypt, Tunisia and Libya. the Emiratis and Saudis have sought to crush popular uprisings against long-entrenched leaders and the systems that they serve.
There are obvious dangers to turning the Sudanese revolution into a proxy struggle between Saudis and Emiratis against Turkey and Qatar
Right now, it's Sudan's turn. Their plan is two-fold: to buttress and arm the key men in the military who are negotiating with the protesters, and use the civilian leaders who emerge to clear all the Islamists out of the army, government, civil service and courts.
Once they achieve that, their Sudanese strongman takes over. It's straight from the Egyptian or indeed the Libyan playbook. What they absolutely do not want is for an independent, representative civilian government to stutter back to life in Sudan.
They have one asset Sudan desperately needs, after the departure of most of its oil revenue, and that is money.
For decades, the only way of getting money transfers in and out of Sudan (American economic and trade sanctions were only lifted two years ago) was through two banks: one Saudi owned, the Faisal Islamic Bank of Sudan, and the other Emirati: National Bank of Abu Dhabi.
Why are Sudanese protesting against their government?
Hundreds of people have been taking to the streets of a series of towns and cities in Sudan since 19 December 2018 to protest a government decision to remove subsidies on wheat and electricity.
Sudan's economy has been struggling over the past decade with inflation spiking to around 70 percent over the past year alone.
This has caused the price of bread to double, cash shortages and salaries left unpaid. The austerity measures adopted by the government are part of larger economic reforms proposed by the International Monetary Fund (IMF).
The mobilisation on the ground against the price hikes - organised by a group known as the Sudanese Professionals Association (SPA) - found almost immediate resonance among opposition leaders, youth and women movements and rapidly turned into a larger show of discontent with 75-year-old President Omar al-Bashir.
Protesters have been reportedly chanting "freedom, peace, justice” and “revolution is the people’s choice” as they march through the streets of the capital, Khartoum.
Sudan's armed forces have responded to protesters with tear gas and at times, live ammunition, mowing down at least 30 people, according to government figures.
Human Rights Watch, the international rights watchdog, says the death toll is closer to 51.
The protests have energised the Sudanese diaspora culminating in the biggest ever challenge to Bashir's rule since he took over the country in 1989.
The end of sanctions failed to bring relief and even when the former president, Omar al-Bashir, came under strong domestic pressure to pull out Sudanese troops out of Yemen, where they constituted the bulk of the foreign fighters, he couldn’t because he needed the money.
Like most of Saudi’s neighbours, he was also fearful of the loss of income from the cohorts of Sudanese expats working in the kingdom.
The tentacles of Saudi and Emirati influence reach far and their links were forged long ago.
One member of the Saudi-Emirati delegation is reported to be Taha Othman al-Hussein. Al-Hussein was a Sudanese intelligence officer who came to Bashir’s notice by uncovering an alleged coup attempt for a former head of Sudanese intelligence, Salah Gosh.
He quickly became Bashir’s right hand man. "I am not the director of President Al-Bashir’s office but rather his son," he once said.
The next Sisi or Haftar of Sudan is already primed, ready and waiting
Al-Hussein used to shuttle back and forward between Saudi Arabia and the Emirates, and soon became known as the Saudis' man in Sudan. He was credited with reviving the UAE presence in Sudan and for smoothing the way for a visit to the UAE by Bashir in 2016.
When Saudi Crown Prince Mohammed bin Salman needed a mentor in Africa, al-Hussein was the man. He also took credit for the decision to lift US sanctions after a visit to Washington to meet members of congress.
Al-Hussein was dismissed in dramatic circumstances. He was arrested at the airport as he was about to board a plane for Riyadh in June 2017 - one month after the official Qatari news agency was hacked, diplomatic ties were cut, and the Gulf blockade against Qatar started.
On him were thought to be documents which the Saudis and the Emiratis needed in their claim that Qatar supported terrorism.
Al-Hussein was allowed to leave Sudan, but today he is back.
A bloody past
Mohamed Hamdan Dagalo, better known by his nickname Hemeti, is another general whose past seems to have been wiped clean but who is central to the Emirati plan for Sudan.
Hemeti, the commander of the paramilitary group called the Rapid Support Forces, came to the attention of the sit-in as a good guy by claiming he had been ordered to clear the square of protesters irrespective of the cost of human life. He refused and put his commander under arrest, establishing a transitional military council.
Hemeti built up a strong relationship with the Saudis and Emiratis in Yemen, as the RSF provided the core of Sudanese soldiers fighting the Houthis
Since then Hemeti has entered the hearts of the square, and as deputy head of the military council he is wielding influence on negotiations with the Sudanese Professionals Association ( SPA) and the Forces for the Declaration of Freedom and Change (FDFC) both of whom are negotiating on behalf of the protesters.
But should he really be there?
Hemeti has a very bloody past, as Sudan watcher Eric Reeves points out in his blog. The deputy leader of the military council is not one of the five Sudanese - including Bashir - for which the International Criminal Council (ICC) has issued arrest warrants over the massacre of unarmed villagers in Darfur.
But Human Rights Watch, which had documented serious crimes by the Rapid Support Forces in Darfur, said that Hemeti’s new role should not make him immune to accountability for the crimes of the forces he commanded.
