While Tazmara, Marius and Jessica drag the boat ashore, Hewitt has enough time to perform whatever ritual he was performing. Laurelata keeps watch, but sees nothing untoward until suddenly an obviously extraplanar black wolf appears next to Hewitt. It seems partially on fire and smoke comes out of its fur now and again, but it does not appear to be threatening anyone just yet and Hewitt seems not the least surprised. After the wolf is properly introduced, the next business seems to be getting the canoe onshore. This probably could be done with a grappling hook attached to a rope, but to prevent quite possible damage to canoe, Taz instead takes rope and dives in. She is trying to tie the rope to the canoe when a small crab-like claw appears from under it, trying to grab her. Soon after, before Tazmara could react to the surprise, a second claw appears and the claws both attempt to grab Tazmara's hand. One succeeds at pinching one of her fingers quite painfully for 1 damage.

I assume Hewitt introduces his eidolon and/or addresses Marius' questions before Tazmara goes diving.
