Update: earlier today I was working on, basically, some energy residues in a place where some very bad things happened, some soul-fragments (as such things are described in the core shamanism model) had also been lost in that location, and it had affected subsequent incarnations (or however you wish to term it) of that person, and others associated as well.
The Angel of Lost Things energy spontaneously manifested in the form of a female nature spirit and the spirit told me her name was ISOLANTHE: I know what “iso” means but when I looked up “lanthe” I got “flower” for “anthe”, which is pretty interesting because while the Angel as above resonates with pink, ISOLANTHE form was dressed like a kind of archetypal fairy, in violets and soft greens.
And there is the common portrayal of chakras/energy centres in the body as blossoming flowers: ISOLANTHE is heavily connected to soul-loss, loss of aspects of the self, and past-life maiming and wounding that carries forward and affects this present lifetime. 
It’s also an opening for researching civilisations that may have existed and been concealed or lost, something I covered earlier here: Things our society has lost or forgotten: could true magick be one?
I am currently researching this area and although the work I did on the property was far more personal and close to home, that which is within, is like that which is without… and the personal, as we have all been told, is always the political. 
Anyway: ISOLANTHE - loong EEEE sound on that first I which is the syllable which is emphasised, “lan theh” is the correct pronunciation given, this is an aspect of the Angel of Lost Things and may also usefully assist people who have suffered explicitly personal losses affecting them on a spiritual, or emotional, level.
Although not an enn (which come from modern demonolatry) I was also given this summoning for ISOLANTHE:
NEKKOMMEN HEHRA TELIS ISOLANTHE

I don’t know what that means or why the words work, but I was strongly pushed to include it here.
