Mmm, since you called my name, I’ll give my 2 cents on this. Hmm, I don’t recall saying these things but maybe I did in the past.
So, activating the sigil on an item ties the servitor to the physical item. Their programming makes them as much part of the item as the item itself. It is their physical home; tie to this realm.
There are certain things automatically programmed into them such as can’t hurt owner, sleep when not being used, ext… These sorts of things are integral to their programming and the way these servitors are made. It is pat of their base being/intelligence and is what they always revert to, to maintain stability.
Sometime last year, someone came to me saying that they told their servitors to move to another item. We gave it a look and they stayed some time in the new items but reverted back to the old items after a short period of time.
I do think it’s possible for servitors to be transferred to another home but long term copy stability tends to accumulate errors over time. So doing this is likely to mess with programming/stability in the future.
