I'd like to preface this by saying that I enjoy the current Alchemy Room. I mean, just look at it. You got your fan to spin on, your stranger who sells you body colours and eyes (which is really weird when you think about it) and two alchemy machines.
But wait. Doesn't that sound kind of redundant?
Now I'm sure a few people out there prefer the comfort of their own guild hall, and hate to leave it just to load up Haven and have to grudgingly walk what is most likely a few feet to that big red alchemy machine, so why can't we have a sprite food machine?
You can already get your own personal Auction House and a training hall.

Now you're probably thinking "Dreemurr, it would probably look awful, I deeply care about aesthetics and am therefore repulsed by this idea.", well hypothetical question, I can show you with the power of awful photo editing.
Behold.

Just look at that, you've got a mixture of red, green, and blue all packed together in an otherwise uniform room, giving it a nice splash of color.

And all it requires is swapping a single model around.

Alternatively, why not have a miniature laboratory to stick in your guild hall? It would contain both a sprite food machine and your own personal biotech member, who will sell you harnesses for your sprites. The room itself would look like a condensed laboratory, with a couple of sprite boxes stacked up in a corner, a few beakers and science-y stuff strewn here and there, and a computer or two parked on a table.
