Ignition Cylinder Broken?

[Organism_ike]

The other day i was starting my 83 (Tilt Column) repeatedly for some tuning. I put the key in the ignition cylinder, rotated it to on, then rotated it forward to the start position, and before the engine even fired the cylinder made a snap and continued to rotate past start, to where it behaved as if it was in the "accessory" position (radio worked, but distributor had no power), and the key could slide in and out of the lock freely, but the cylinder wouldn't rotate back to any of the positions it is supposed to. In other words, the key was stuck past the start position, the battery stayed on, and when rotating the key forward the cylinder felt springy like it normally would when rotating it to "Start" and the starter would kick on, but when I released the key it would go back to the "too far forward/broken" position and the engine would die since it thinks it's in "accessory" position.

Yes, I tried moving the gear selector to each position, along with a few other obvious tricks. All I need to know is if the ignition cylinder is broken, or is it something else? I unplugged the battery to stop the drain.
