Astrid:
Let's just put him down, gently.
Kestrel nods at the mage's suggestion, but does not move his rope. Once the bear has fallen into slumber, Kestrel asks Astrid,
"How long will this last?"
He will slip rope through the collar and tie it off at the nearest large tree or boulder.
"With only a few minutes before the spell ends, and given how dark it is, we are best to move far enough that Boddynock, here cannot reach our packs. Perhaps we should build our fire up too?
Astrid, when the bear wakes, I suggest you speak to him in gnomish, it may calm him."
Looking to the other ranger, Kestrel calls out,
"Don't wander too far, Ulle, the night is still young."
As he moves his own things away from the bear, he leaves the rations next to the bear. He also gives Kossoth a gentle shake, to wake the warrior.
"Kossoth, be aware, we have a bear for company!"
As he settles back to rest, he ponders,
"A bear tamed by a gnome...I wonder if Boddynock's owner has run into problems with the kobolds that Birahu mentioned?"
If the watches run from 10pm to 6am; this all occurred at 1am so it is probably pitch-black! Also given that the DM has said that elves require only 4 hours of reverie Kestrel can be part of watch 3 as well as 4.
