Don't know about modding, but you can edit it in (at least, you can in the demo....) if you have a hex editor:
with the ftherlnd file in the save directory:
search out the name of the pretender(s) you want to have the gobs of gems, then back up a ways; there should be a long series of FF's (58 (hex, 88 decimal) of them) fairly soon; from the first byte of those FF's, back up 36 (that's in hex - 54 decimal) bytes, and you *should* be at the start of the gem supply, two bytes each, low byte first, ordered Fire, Air, Water, Earth, Astral, Death, Nature, Blood Slaves.
Then save and exit the hex editor.
Then host, without running your turn (the turn file would either eliminate that particular change or give a corrupted error message - not sure which).

That gives it to you on turn 2....
