If you're like me and always keep your in game map open, it will leave a nifty waypoint when you use the power, in addition to keeping a circle around the power and changing the image of the power in your power tray after successful activation.
You'll want to place the tp location you want to go back to (mark) near the entry door. Then once the npc escort target changes from blue to green, that means it's following you. Then just hit the Accolade Power again (recall) and you'll be back at the entrance with the NPC. Doesn't work with non-attacking grey/white NPCs.
Fun uses includes getting Becky the Tarantula in the first mission of the ASF to the back easily. And during daily GM hunts on Indom when we go in to Boomtown, I'll place a mark at GWW while the league goes to Babbage. Once the league defeats Babbage, I'll recall then incan the league to GWW.
