I never said the whole Legion was on Terra xD Arcadese is the only Ultramarine present, apart from (maybe) Tetrarch Tauro Nicodemus (also seen in Age of Darkness). Arcadese was a Sergeant who fell in a coma during Ullanor Battle and awakened after the Istvaan V Massacre. He and a Salamander survivor were sent as speakers in a diplomatic mission to convince the world of Bastion to stay with the Emperor instead of joining Horus. After a series of events I won't spoil you, he seems to have returned to Terra to report the results of that mission.
