- "I am never alone: my thoughts are always among the stars."
- – Draal
Draal, a member of the Minbari Religious Caste, was a teacher and philosopher on Minbar. One of his students was Delenn, with whom he would maintain a close friendship. Apparently, he was also close friends with Rathenn.
Over the years, he had become disillusioned with the state of affairs on Minbar and his people in general - believing that they had lost their way. Feeling utterly useless back home, he decided that it was his time to go to the "sea of stars." In 2258 he decided to travel to see Delenn for one last time before he died.
During his visit, the planet located near Babylon 5, Epsilon III, began experience a great amount of geological activity, and it was soon discovered that there was a huge machine built beneath the planet's surface, the Great Machine. The current occupant of the machine, Varn was dying and needed to have someone replace him within the machine. Varn appealed to Draal, knowing him to be a suitable replacement. Draal decided to take his place within the machine to keep it functioning. Delenn and Londo Mollari arranged to get him back to the Machine. Once joined with it, Draal issued an edict forbidding anyone from landing on the planet, threatening deadly force in retaliation.  
A short while later the Earth Alliance station Babylon 4 reappeared in Sector 14 through a Time rift. Though unknown to anyone but the Vorlons at the time (with whom Draal had been in communication) it was Draal who closed the rift after the station vanished again, but prevented it from closing all the way as the Vorlons said it had "value". 
The Machine nourished and rejuvenated Draal, restoring to him his youth and appearance of thirty years prior, invigorating him for his role as the Guardian. His mind reached out across the stars, as the Great Machine let him see and hear things from all across the galaxy. After a year of learning and observation, he contacted Delenn and Captain John Sheridan via a holographic message, inviting them to come down for a visit. Once on the planet, Draal pledges his service to Sheridan in an alliance for the upcoming Shadow War.
In 2260, as the new War Council is in its formative stages, Delenn asks Draal to help the crew of Babylon 5 fight the Shadows by helping track down the remaining First Ones. With Captain Sheridan busy dealing with a snooping EarthGov representative, Susan Ivanova travels to Epsilon III to work with Draal in his stead. Draal takes an immediate liking to the feisty Ivanova. He allows her to step into the Great Machine, allowing her mind to stretch out across the stars. She finds a trace of them at Sigma 957, but the Shadows become aware of her and try to interfere. Before disconnecting herself, she manages to get a copy of transmission of then Vice President Morgan Clark admitting his part in the death of President Luis Santiago. Draal copies it at Susan's request.
