[OB] Oathgate seen in interlude:

[Sirscott13 he/him]

From interlude Lhan I-12 words of radiance

"They passed into the Circle of Memories, a round room with ten lamps on the walls, one for each of the ancient Epoch Kingdoms. An eleventh lamp represented the Tranquiline Halls, and a large ceremonial keyhole set into the wall represented the need for ardent s to ignore borders, and look only at the hearts of men . . . Or something like that. He wasn't sure, honestly."

 

Does this description not sound like an oayhgate? Makes for a pretty interesting location given the outcome of the interlude.

It's been brought up before, and the Oathgate is supposed to have been built into the Palace itself. That's almost certainly it. 

[Steeldancer he/him]

Never noticed that before.
