Hey, can Holy Sites be upgraded?  Say, I put eight might toward making the Astral Home a 10-M holy site, combining with the two already had, that gives me five per turn.

Nope, the only way you can upgrade an existing holy site is if it was destroyed/damaged in some way. Whatever Might is put into repairing it becomes the new figure. The previous Might used to create it is not counted. See Orabil as an example, 6 Might was used to create it (providing 3 Might per turn), then it was destroyed and repaired with 12 Might. That means that 12 Might is the new figure (6 Might per turn) rather than 18 Might (original 6 Might plus 12 Might for repair)

[@Hael] Black magic? I wouldn't know anyone who could've done that...
