Like the forms the shades would take if they were summoned, and then, behind those forms, the rough outlines of the avatars of those powers.

Well, it's something to do. What does she look like through this mirror?

A writhing mass of tentacles, each topped with what feels like a strange oblong section. The tentacles are constantly reaching out as if pointing into the distance. Sometimes when they do so the oblong sections pop off and vanish only to reappear and reconnect seconds later. It's difficult to guess at what exactly those sections are with just the feeling sense the Fairy Queen has for the unmanifested shades. 

Two of the tentacles are relatively still, each pointing in a different direction.

In her house at Glaistig Uaine dead Scout writhes, pointing. Wow.

Is the Queen up to anything more interesting now that she's gotten distracted for a bit?

She's working with three shades to simultenously reinforce and redecorate one of the cells. One shade gives her architectural advice, one burns the concrete with colored fire that changes its properties as requested, and one smooths over the results with unseen waves that render the effects safe and permanent.

Lorica'd wonder where she's getting these but apparently she's getting 'em by magically reaching out of the Birdcage to grab anybody dead with a neat power. Whose cell is it?

It's empty at the moment, though there are some people down the hall whispering about who should get it once she's done

Lorica's cratered opinion of the Fairy Queen ticks up a little tiny bit.

She ends up transforming much of the wall into a rubylike red with veins of gold - in the corners the gold emerges from the wall to hold individual gems aloft, each containing a flickering glow to illuminate the room. The bedframe likewise becomes gold. Most of this is done with the three initial spirits, though the gold portion of the torches requires a fourth who also helps grow the bedframe into a more ornate form. 

Interior decoration is such a nice hobby to have in a horrible inhumane prison.

An energetic young woman and a dour older one end up negotating their way into being the residents of the new cell, trading away stockpiled rations to do so. 

What do the folks who have to eat even get, around here.

Canned meats and vegetables, bread, crackers, and both hard candy and chocolate. 

Well, ?fortunately?, shades don't appear to eat, so she does not need to mourn the absence of ice cream and fruit and whatnot an additional time due to being in the Birdcage, just the once due to being dead. Except insofar as maybe Glaistig Uaine eats and she could piggyback on that? She hasn't caught her at it yet.

The Fairy Queen does eventually partake in a dinner, which is apparently half a can of salmon on top of a single slice of bread, eaten meticulously with a fork and knife in a dining room with wrought iron tables and a chandelier that looks entirely mundane through normal sight. However, through the Fairy Queen's power sight the bulbs look almost like three dimensional blueprints.

Must be tinkertech. Can Lorica tell what they do?

Yeah, that bit is a powersource and that bit defuses microwaves and that -

Be warned that if you overuse your fairy's knowledge when I am not providing power for you, you may empty your well and find your mind without the protection your fairy typically provides.

.......

Thanks

You are most welcome.

How much use is overuse?

Right now half of an hour would drain you, though that number will grow when I fill your well. It is possible your fairy would simply switch off your brain should it run out - I cannot read its intentions exactly.

Okay. Is that only for tinkering in particular?

Any of your powers will do it - even the protection would drain itself eventually, though not for years. However you can continue to make use of my senses without fear it will impact your fairy.

Thanks she repeats.

Okay, no staring at the lights. How about she tries to learn everybody's names and the layout of the prison and stuff. And looks at the... fairies.
