@V2Blast The party was going to leave you as a rear guard for a bit too long, so I applied a little "passive presence" guidance and they picked up on it immediately. Laz closed out pursuit by using sickening radiance, the nereid got whacked so Velthiss summoned two giant octopi who did an admirable job of covering your withdrawal as the "GONG!" sound propagated through the deep water.
As you left the passage with the sounds of chaotic pursuit behind you, you noticed 11 Tritons with lances and 11 Tritons with heavy cross bows approaching the opening; they barely acknowledged your passage.
