Eren will start the Jaunt Infiltrating, although his name will still simply be Eren. He primarily works as a guard-for-higher for merchant caravans. This means he's been all over the Vale and has plenty of casual acquaintances, but has very few real friends because of it. Originally from Fallen Wrath, Katadors might recognize him as a promising trainee who very loudly and dramatically quit the training program a few years back. He was training under the warband that both Ioskelaino and Kleio were a part of. Deciding he didn't want to be angry all the time combined with Ios' everything made him disenchanted with being a Katador, and he made sure people knew that was a big part of why he quit right after Kleio left.

I plan on this overlay dying around halfway through the Jaunt. After which Eren will be around as himself, which should create plenty of opportunities for shenanigans when people inevitably mistake him for his dead overlay. Especially when he's going to be throwing himself into the efforts to make things better for this world. The moment subtlety gets in the way of helping these people any attempts at subtlety from him will be thoroughly defenestrated.
