Discovery, Exploration

Anjor Disappears from Toril for a time. Torandar Giantsbane discoverd a Black Obelisk deep in the High Forest. He returns what seems like minutes later but he spent several decades in Netheril.

Anjor Disappears from Toril for a time. Due to the efforts of the Company of Luck and Light, Anjor learned of the Black Chronology. He was not sure Shar's plans were defeated, so he went back to Netheril to find solutions to the possible calamity. He returns what seems like minutes later but he spent several decades in Netheril.
  Torandar Giantsbane discoverd a Black Obelisk deep in the High Forest. Anjor studied it and realized with his Staff of the Magi he could activate it. This brought him back in time to Netheril, before the fall of Karsus. While there he learned a great deal about Netherese Magic and was able to discern a great deal about the possibility of a Spellplague due to a collision of worlds. He spent a few years formulating contingencies. He returns what seems like minutes later but he spent several decades in Netheril.
  The Obelisk was not at the same location when he went back in time, but being familiar with Portals, Anjor travelled to Sigil. There he met his old friend an Ancient Time Dragon, who brought him back to the point of time he left Faerun.
