move the older 13th Age and Cypher System stuff for Adventuring!

these were both in the homebrew setting that never got off the ground.
these were replaced with a Forgotten Realms-based Cypher System game,
which is soon to be moved to 13th Age 2e, so I'm cleaning up the old
stuff before I figure out what to do with the current (soon old) stuff

+# Yacsra
+
+Yacsra is my *yet another campaign setting, roughly assembled*. Made to organize elements of my
+various 13th Age games, its exact theme and purpose is malleable and inspecific, subject to my and
+my players' whims, and no more exact than whatever interesting thing comes our way. That said, the
+goal is that certain established (for now...) truths are catalogued here for reference or usage in
+other campaigns.
+
+## The Icons
+
+### A Cat
+
+### Erthu
+
+### Felt Fish
+
+### Kobu
+
+Kobu, the Faceless, is known to "steal faces".
+
+*Domains:* stealth, espionage, thievery
+
+### Maggot
+
+### Pulgasari
+
+### Savage
+
+Savage is known to be a massive, muscular human, adorned in the hides and skins of humanoids, some of which they consider
+to be trophies. Savage's followers tend to be humanoid monsters, barbarians, and the like. The cliffs notes for Savage
+read, simply, "evil Conan".
+
+*Domains:* war, domination
+
+#### Lore
+
+* Years ago, a tribe of barbarians following Savage waged war on one of the principal banks of Erthu, leading to a deep
+  enmity between the two icons and their followers. Many of the fallen barbarians were buried in various graves
+  throughout the region of Blackmond.
+
+### Tersgot
+
+### The Eye
+
+### The Ring
+
+The Ring is believed to be a gnome whose consciousness has been overtaken by a psychodelic cordyceps, generally held to
+be altering the consciousness of and influencing, corrupting, or expanding --- depending on who you ask --- the minds of
+his (its?) followers and those around him (it?).
+
+*Domains:* ?
