Find the place? Easy, especially for the Unchained, whose control over Space grew and grew as each passing day went by. Near to the place where it was all to happen, Alastor waited for the others. He stared off into the distance and imagined a huge square around the place, a little perimeter to alert him as to comings and goings, and pealing out the words of power made manifest the First Talon's will so that he would know when a being was coming or going from his gigantic square of detection.
Naturally, Alastor was well-prepared. His vicious kusuri-gama on his hip and his shotgun slung over one shoulder, with his undercover vest on beneath a simple black t-shirt, the ensemble was completed with aviators, rugged black cargo pants and a set of athletic shoes. A combat knife was strapped to the inside of his ankle and his cellular telephone was set to silent in his pocket.
Patience.
The others would be here soon.
Just to register it at the outset:
1) Equipment is listed in narration above.
2) Rituals are in the character sheet.
3) Whenever we're in appropriate range, Alastor will cast a 256 yard radius Intrusion Warning around the greater property. I would, if it's acceptable, like to include Mind 1 conjunctional piece to allow him to restrict the Warning to detect whenever creatures capable of sentient thought cross the barrier. If that is not acceptable, then I'll restrict the Warning to ping me whenever a creature of size 2 or less comes or goes through the barrier. The idea of the spell is to let me know and where something is breaching the line so we can pursue if need be. What works for you?
