hidden resources uncovered

Incidentally or accidentally the following covenant resources have been uncovered from the beginning:
Wall decorations of Temples 2 &3- insight potential undocumented level since nobody has explored this (unknown BP value)
Vis source- It has been discovered that burning dead animals in the crematorium (in temple 1) can provide 4 ignem vis on the summer solstice, 4 vim vis n the winter solstice, 4 animal vis on the spring Equinox and 4 perdo vis on the autumn equinox. (80 BP)
The lake which was created with special insight from the magic realm apparently has fish which should not be there. These fish provide 10 Aq vis per year (50 BP)
