Theren has spent most of his time observing the other members of the caravan, since it had been 100 years since he has had any interaction with anyone outside of the monks of the cloister.  He has lent help whenever it was needed though, including any minor first aid and taking turns on night watch, something that is particularly easy for him since he only needs to meditate 4 hours each night to be well rested for the next day.
