Astrotemple

One of 3 strange temples in Costrana that bear signs of the god Celestian. Researchers from Talonor have long searched for an entry point or a way to breach the magic of the tower. None have succeeded. The temple is one of 3 suspected by mages, as cave art found near Copper Pass show 3 towers. However, only 2 have been found.
Celestian has been depicted as many things in the scriptures of old, but most show him as shown above (or a variation of it).
