Actually, I just calculated the costs for supplies (we feed the guide), if we go to Ixab, there are no sandstorms, and the journey to Ammu-Ay also takes a week. That comes out to at least 420 rems. It's feasible in theory, but the finances will be tight with tournament purchases, unless a new raven arrives with new funding (I suspect it won't, since this one is with us until the end).
