Bastion
Uther - Confirmed in Bastion for his valor and servitude to the Light.
Tirion - While it first seemed his soul was burned by the Fel at the Broken Shore, the Paladin Class campaign in Legion revealed he later died from his wounds, not from his soul being fel-burned. This would mean his soul could travel to Bastion.
Durotan - His honor in life, dedication to his people staying uncorrupted, and putting himself in harms way so others may live, would earn him a place in Bastion.
Rhonin - Sacrificed himself so others may live, and dedicated to the pursuits of knowledge and bringing peace to Azeroth.
Revendreth
Kael'thas - Confirmed in Revendreth to atone for his hubris and megalomania.
General Brigitte Abbendis - The Scarlet Crusade / Scarlet Onslaught were devoted for certain, but devotion without valor just results in wrathful vanity.
Antonidas - While usually a kind and a wise teacher, Antonidas was also prideful, and quite dismissive of others. If he went to Revendreth, it is likely he's already near the end of his penance by the time we meet him.
Daelin Proudmoore - Blinded by hatred towards an entire race, it's likely he's doing pennance for that.
Othmar Garithos - Move over, Daelin. Hatred towards one race? How about hatred towards all races other than your own? Garithos is likely being feasted upon by Revendreth's denizens and wont be done for a long time.
Majordomo Staghelm - Prideful and vain, and betrayed his people in exchange for power.
Ardenweald
Cenarius - Semi-Confirmed in Ardenweald. Is currently "alive" in the Emerald Dream, but may potentially be free to travel between Day/Summer (Emerald Dream) and Night/Winter (Ardenweald).
Agamaggan - Absent from Azeroth for the longest time. Thats one hell of a sleepy pig.
Cairne Bloodhoof - Noble and strong and -like most tauren- deeply connected to the natural world. If there is an eternal hearth of ancestors, it is likely located in the autumnal fields of Ardenweald.
Maldraxxus
Draka - Confirmed in Maldraxxus for her commitment to strength and growth in power from a sickly orc to a fierce warrior
Anduin Lothar- Despite being a Paladin, Lothar's military might and prestige would earn him a commanding place amongst the Shadowlands' standing armies, which are housed here.
Orgrim Doomhammer - Likely vying for power and influence in Maldraxxus with Lothar, which would be quite fun to see.
Grom Hellscream - Might makes right, and Grom was one of the mightiest. While his death was bastion-worthy valorous, his life was one of constant battle. If given the choice, he wouldn't give Bastion a second glance.
The Maw
Saurfang - Likely in The Maw, his death is post-WoD, which currently seems to be the moment where the Engine of Death broke.
Varian - Uncertain. If a living creature is destroyed by the Fel, does the soul get consumed in the process (similar to fueling the Legion's soul engines)? If yes, Varian has ceased to be. If not, his soul is in the Maw due to the broken engine of Death.
Gul'dan - See Varian, except he actually belongs here.
Arthas - Completely corrupted by his pride. While a victim of Frostmourne, many of the decisions leading to where he ended up were still his own.
Xavius - Empowered by the Legion, yet loyal to the Old Gods, there is no redemption for him.
Grand Apothecary Putress - Betrayer, mass murderer, sycophant.
Shadowlands (Other)
Rastakhan - Likely in Bwonsamdi's pocket dimension, De Other Side.
Vol'jin - A special case. "Touched by the Hand of Valor" would indicate a connection to Bastion, but I'm thinking it may be the Arbiter who empowered him, if she is aware of the Jailer's plans. He may be in the Shadowlands, but it doesnt seem he's bound to it like the others are.
Not in the Shadowlands
Kel'thuzad - Unlikely. Upon his defeat in WotLK, his Phylactery was never found, unlike when we defeated him at lvl 60.
Ner'zhul (Alternate Draenor) - Since Draenor is in another reality / timeline, and he died there while also belonging there, it is likely he ended up in that Reality / timeline's Shadowlands. While all Realities' Shadowlands may be one and the same, without a Dark Portal in the Shadowlands connecting that, it is likely a "layer" ontop of ours which we cannot interact with. (lol layering)
Medivh - Seems to have stepped outside of the Circle of Life and Death and is apparently free to roam Azeroth. Is he a spirit? Is he something more? It hasn't been explained and Kadghar has been just as confused about it as we are.
Aegwynn - Most likely? See Medivh.
Garrosh - Like Ner'zhul, those who died in Alternate Dreanor are likely only to be found in that "reality layer" of the Shadowlands. However, his spirit did originally belong to our reality, so unlike Alternate Ner'zhul, this may not be the case for Garrosh.
Emperor Thaurissan - His Spirit is roaming Azeroth still, found in Blackwing Descent
