Created a strange Stone. I'm calling it the 'myst stone'. What does it do?

[VoxelV]

Hello, this is my first post on giantitp.

I am playing a custom d&d 3.5e campaign.

TL;DR
Found a strange stone. What does it do? Help!

Long Version:
(Ingame) We were about to bed down in a building in the Undead sector of TerranTool (A floating City). Our party is escorting an NPC Pelor cleric through the sector so he can purify specific buildings.
Apparently the world has areas affected by "Myst", a strange dark cloud stuff that people go in, and don't come back, or people come out and cause havoc, or has effects on surrounding areas.

Anyway, we happened to be near a small vortex of this "Myst", so the cleric pointed it out. Here's what I can remember happened.

=============================================

Myst Stone:

Before, a tossed stone into a myst vortex which re-appeared behind us as if tossed similarly.

Obtained by tossing a stone into a myst vortex and "one in a million" chanced to hit
the "anchor" of the vortex. The vortex was absorbed into the stone.

Phases through hands, but with some resistance, so that you can 'juggle' it into the air.
Does not phase through adamantium, so juggled it into an adamantium box.

Appears to be linked to a golf-ball sized distortion that was about 10 meters away.
When myst stone was close to the distortion, it moved toward the distortion.
Moved the myst stone away from the distortion so it wouldn't be drawn to it.

Grabbed some sand and poured it into the distortion.
Sand appeared in the adamantium box, but less than was poured into the distortion.

Dropped a rock into the distortion. Nothing. Grabbed another rock and did the same.
Deja Vu, it appeared I put the same rock into the myst stone.

Grabbed a plank from the street and pushed it against the myst stone. A notch was missing
from the plank after that.

Grabbed 100 sticks and started putting one by one into the myst stone. Each one
seemed the same as the previous stick (Deja Vu). Confirmed something time-related
was happening.

Grabbed a bunch of rocks. Marked a rock with chalk and set it on a chalk mark on
the ground. Put another rock into the myst stone and moved the marked rock off the
chalk mark. Everything was normal.

Put a chalk-marked rock into the myst stone. Something about chalk washing off
after 500 years.

Etched an 'M' into a rock. Put it into the myst stone. Put another rock into the
myst stone. No Deja Vu. Put another rock into the myst stone. It felt like that
rock had something etched into it, but I didn't catch it in time.

Repeated that, and etched another rock and put it in the myst stone.
Put another rock into the myst stone. No Deja Vu. Checked the next rock.
Nothing strange. Etched several rocks and put several in. The rocks in my
pile seemed to be smaller than before.

Found a mundane crystal shard in my inventory, put it into the myst stone.
Found it nearby (not at the distortion) and it had turned into obsidian.
Tried putting the obsidian into the myst stone and it got stuck and was
spit back out.

=============================================

Anyway. Any ideas on how else to test this, or thoughts about what it is or how to use it would be appreciated!

Thanks,

Ask the DM about it. What level was this designed for? Maybe an identify spell would help.

I agree. Sounds like your DM is having some fun. Gonna have to suss this out in the game. :D Sounds like a fun interesting item...

Wonder what would happen if you dropped a fireball bead into it... *blinks innocently*

Sounds like a wormhole through time. Probably ~500 years into the past.



Pushing a plank up against it carves a notch out of the plank. This sounds like the part of the plank that was "inside" the stone simply aged away.
Chalk-marked rock put into it provokes a comment about chalk washing off after 500 years? This sounds like a hint about the time difference.
Sand poured into the stone causes a lesser quantity to appear. Sand erodes over time.
After putting an etched stone in, and trying to put another one in the second one might have had something etched on it but you couldn't be sure. The first stone you put in with the M etched into it went 500 years into the past, and the etching eroded away in ensuing 5 centuries. You happened to pick it up again.
The rocks in your pile seemed smaller because you sent them 500 years back in time.
People going into clouds of "myst" and never being seen again, or people coming out of them, are those who are unwillingly traveling through time.

Clearly, this means he needs to shove an Elf into it to test the hypothesis.
