OOC:-_- Alright, you wanna play that game? Fiiiiine, then, we can play that game. I don't like to 'cause its not very fun, but fine. I don't mean any of this personally, if any of this post comes off as insulting then I'm sincerely sorry, and I don't mean any of it that way. But that whole 'Phoenix can burn aaaaannnnnnyyyyyything' thing? Really? I am sorry, but that's literally the cheapest and onethe of thethe most uncreative moves in the book, well right next to just saying,"Sorry, but my attack works anyways and oh I'm not gonna bother saying why".
Of course, since the tree wasn't growing at the speed of frikkin' light, it wouldn't reach forest size the time the Queen noticed. And its not like they had to TRY very hard to get the Queen's flesh off, I mean, its a biological reaction she is able to consciously control, no digging and tearing at the flesh necessary. So, of course, it was long gone by the time it was a tree, let alone a forest, and if it kept trying, it was as you said corporeal, soooo a psychic shove would be more than enough to keep it at bay, it never losing momentum as it'd just drift out of their system far, far away.
Alright...Congratulations on trapping the Marid? I mean its not like the Lorcar would've made the barrier bowl shaped with the convex side being the Lorcar and Convex being Marid...The intent was to prevent any of the field from getting out, so they'd have made it cover everywhere 360 degrees around, and you outright said nothing can get through from both sides, so...I don't think that the Lorcar would feel the need to bother with it anymore, threat contained, and its still filling with that MDD Field which is eventually force its way into the Madrid's 'bubbles' without anywhere else to go, destroying themselves by filling it with the field and overflowing it, so there's that too.
As for the snakes of Holy Psychic Fire...The Lorcar would just exert control over them, since they're made of...Y'know...Psychic force, and not even a great deal of it. This Psychic force would be pretty easy to control, seeing as the Lorcar were just a little adept at using, and by extension repurposing, Psychic power itself. Absorbing the psychic power, incorporating it into the snakes themselves, that just gave the Lorcar something they could feel with their mind, see through their Mind's Eye, and take hold in order to suit their needs. They wouldn't burn after the Lorcar Bioships at all, instead converted into their own control to use as they'd please.
