I have edited the expenditure in the last post to the following:
--MIGHT & FP EXPENDITURE:
----Creation of the River Seihdhar across Kirron's continent - a minor landscape change.  (-2 Free Points)
----Causing the River Seihdhar to run with Seihdhara's ichor rather than water. (-3 Free Points)
----Giving the River Seihdhar and the Seihdh Lake the properties detailed in the wiki page. (-6 Free Points)
----Making the Source of the River Seihdhar (the lower half of Seihdhara's corpse at the bottom of the Seihdh Lake) a Gateway to the Seal. (-7 Free Points)
0 MP & 0 FP Remaining

Please advise as to whether that is suitable.

Reading the wiki article, it appears that, essentially, the effect of the River Seihdhar is to Bless individuals with blessings appropriate to Martial Combat, plus a some extra pertaining to physical health (if it were entirely under Martial Combat, you could do it for free, but the physical health stuff pushes it just out of the Portfolio discount). I very much like the effects. There is an argument to be made that it can be even cheaper. 'Causing the River Seihdhar to run with Seihdhara's ichor rather than water' could be done as part of the other items rather than as a separate item, so that would save you 3 FP. Note also that the Seihdh Lake gains properties simply by being a Gateway to the Seal. There is no benchmark for something which has the properties you propose, so the number you propose for the properties is as good as any. 6 FP feels good. One could argue that it should fall under a Monument, which puts it at 3 FP but not necessarily powerful enough, but you could hand-wave and say that the River and Lake are separate yet similar and connected Monuments.

P.S. And making things from the chopped up remains of gods is a very traditional thing in mythologies, so it's good that we've got something similar here.
