People want to bitch and moan about how Kelin had a right to go exploring, but he really didn't. As a Maran especially you have things that are expected of you, one of the more important things being the defense of the Fortress and its members. When you swear an oath to defend the Fortress with your life, then run and hide at the first sign of risk, you're not upholding your oath.

If you want to play an explorer, go be a Herald or uncaballed. Being a Maran carries some pretty serious responsibilities to go with the beefy powers, as it should. Being a Maran and an Explorer who is out of touch with his comrades for 3/4ths or more of his time just isn't compatible.
