Do you have a Sesh glyph?
They’re very useful, if you can acquire one — many archivists and scriveners and sages of all stripes have one, as do most arcanists and more than a few masters of merchant-caravans and curious nobles and busy churchfolk. Sometimes you can buy one, or pay (in coin or kind or stranger things) to have one designed for you, at a curio shop or a scribal hall; and many are those who apprenticed to magic, successfully or no, who received their glyph courtesy of their mentor. They all come from someone who already possesses one, of course, because designing a new glyph requires a Sesh to be present to recognize and accept it.
What’s a Sesh, you ask?
Why, the most convenient of entities. Summon a Sesh — a gnarled little figure the size of a husky housecat, all dull-jewel scales and twisted horns and stubby wings and twisting tail — by drawing your glyph, preferably at the end of some missive or other, and the eldritch little clerk will appear out of the very air, scrollcase clutched in its twisting little talons.
Now pop your letter, or letters, or whatever else you wish, into that scrollcase it offers you, seal it up smartly, and write your glyph on one end of the case and — this is quite important — the glyph of your intended recipient on the other. The Sesh will snatch up the case and its contents and quick as a breath carry it through the nothingness between to the other party.
It’s amazingly convenient, and why, the Sesh asks for nothing but the chance to carry missives, and for only its scrollcases to be used. And that nothing be too large to fit — the case absolutely must be capable of sealing.
It’s a useful, wonderful thing to have in your pocket, as it were, isn’t it?
Just be certain you write the glyphs properly, of course. Your missive will just be brought back, battered and faded and the worse for wear by a very annoyed Sesh.
And check to be certain that there’s no lingering glyphs hanging around, in the bargain. The Sesh will deliver to every glyph indicated, after all; that’s its task and it will see it done.
But you’ll be careful, right?
Oh I do hope you get yourself a glyph soon!
