So a few weeks after D2 launched I managed to complete the heroic public event on titan that involves the Hive attempting to summon a servant of savathun. If activated the public event spawns a night that looks exactly like Alak-Hul the dark blade from Destiny 1, at first I thought it was a nice little nod from Bungie to old Destiny players but then I started thinking... What if the abyssal champion is in fact Alak-Hul? Now I understand this is going to be a stretch but hear me out, I currently have 2 main pieces of evidence 1. The abyssal champion looks exactly like Alak-Hul and I highly doubt he had any fans after he tried to kill Oryx And 2. Alak-Hul might have a throne world Allow me to explain number 2. If you read Alak-Hul's grimoire you find out that he was Oryx's foster son, he was adopted by Oryx and presumably raised by the taken King. Now all of Oryx's children are acendent Hive and because of this each have their own throne world, it's not entirely unbelievable to assume that Alak-Hul also ascended with his "siblings", not that it matters if he's related to Oryx as other being's outside of Oryx's blood line have throne world's (see Omnigal, the Mindbender, the worm gods Etc). This would explain why Oryx imprisoned Alak-Hul instead of killing him, he new that it would be pointless and that Alak-Hul would attempt to take the crown again once he was summoned back into our reality. Oryx decided to lock up Alak-Hul and capture his (potentially) only follower that could summon him back from death, Verok.I would assume then that after killing him, Alak-Hul was stuck in his throne world until savathun decided to free/recruit the dark blade. He then hid his name as the Abyssal Champion to avoid any unwanted attention from Guardians. So that's my theory, again I understand that this is a REALLY huge stretch with very little evidence to support it but I hope you guys enjoyed it.
