The Fountains Of Aescalon. Connected Realms, #1

The first thing Alexan knew was standing over an impossible corpse with an ichor-stained sword. Exiled from home for reasons of politics and health, he has to orient himself in a new home, but he still has the skills he was 'born' with, skills which make him a wizard in his new homeland.  A blasted, sterile cavern has many portals, but the one he chooses leads to the top of a huge tree, the source of magical power for an entire world. Power is plentiful in Aescalon, but those who have it want to keep it all for themselves, and the arrival of a new wizard upsets the balance.  It seems everyone who doesn't attack immediately wants something from him - including a cursed demi-goddess desperate to escape her fate who thinks Alexan may be able to help her. But Alexan can't even help himself until he unravels the secrets of The Fountains of Aescalon   Book One of Connected Realms
