Legendary Creatures

This is the collective name given to all those creatures that started re-appearing after the Elven invasion, but are not part of the Elven contingent. (eg Ogres, Kobolds, Minotaurs and who knows what else. (Harpies, Sahuagin and Lammasu for a start!) (Maybe Dragons?)
We now believe that these were creatures allied to the Wild that 'escaped' through the portals created by Soratan when he cast the (first) Spell of Voids. We cannot say if some 'extra' creatures that were not associated with the Wild went along/got sucked in too.Day 65 - Far Haven - TripwiresZoom 2021-01-07 21:00
We still do not know how they managed to come back, if they came back intentionally or not, or if they have any plans or aims now that they are here.
==Previous Questions==
*Timing of disappearance:
** Did they disappear at exactly the same time as the Elves? See #Week 3 Research Answer: Before
** Did they disappear all at once (like the Elves) or over a period of time? See #Week 3 Research Answer: Presumably quickly through the portals.
** Were they immediately forgotten about, or were people asking/singing 'Where have all the Kobolds gone? Long time passing....' Answer: Depends how quickly the Spell of Forgetting (ie GSOV) took effect.
* How did they get back here and why? Important unanswered question
* What is their connection with the return of the Elves? Ditto
* What can we learn about how to deal with them?
* Are they being controlled or organised by anything?
* Can we ret rid of them? 
* Are there any more on the way...?
The Brooch from the Ogres is about the only clue that we have.
Despite appearing at around same time (well, about 4 or 5 months later) as the main Elven invasion, they are not controlled by the Elves:
"Cagrun: Most importantly, all of them appear to be hostile to the civilised people on the island, even the Elves."Day 7: Return to Braerk
==Week 3 Research==
We now have evidence from Council Record Fragment 2 that the Legendary Creatures' dissapearance may not have been due to the Elves - but rather due to a ritual that 'they' (well, someone/something) performed before the Elves departed themselves.
==Week 2 ResearchResearch (Week 2)==
One student, who appears to be taking a bit of a lead on this summarises what they think they have worked out so far:
* The creatures, and so far they have pulled together a large list of	beasties, whilst not the most organised appear to have been ruled	and given a collective goal – that was inimical to the Elven	Empire;
* The “rulership” would seem not to have been an individual but a	collection of beings – but it is difficult to judge at present who	these were or how they were selected etc.
* They had their own belief structure, although at present little can	be worked out – most of the races had shamans or priests;
* At some point the Elves were in danger of losing. There is talk of a	radical shift in policy in order to meet the threat (note: These	scrolls will be off to Adamas)
==Week 1 Research==
This proves quite a rich source of material, it is soon fairly obvious that to the Elves at least many of the creatures that modern civilisations regard as mythological were real to the Elves. These creatures were regarded with significant dislike (but not disdain).
Within the week your research has identified Ogres as being known to the Elves, described as:
“Brutish footsoldiers of great strength and stamina, they sometimes act as leaders of the lesser spawn but more often are deployed as shock troops. The more intelligent individuals can be shamans, priests or even arcanists – these individuals have the potential to be extremely dangerous and should be eliminated as soon as encountered.”[[Day 21-27 – The second week in Northlake
