The same way Jannequinard does I assume. Also Leveva post level 60 has let anyone who wants to learn Sharlyean Astrology to do so. Which is similar to Geomancy and last I checked the Hingan we meet in the SB questline doesn't have a stone. That and anyone who won a riddle contest that lasted for seven days against pixies probably can find a way to switch from a 1.0 arcanist to Astrologian.
