Soul Keeper

Soul keeper is structure that keeps the dead dwarfs' souls, so they can be resurrected by using a potion of resurrection.

Placement
The soul keeper only works if it's installed before the dwarf's death.

It is one of the largest structures dwarfs can craft. It measures 5 blocks wide by 3 blocks tall.

Outside the shelter
The soul keeper can be placed inside or outside the shelter. Monsters won't try to destroy it. But if placed on blocks placed by dwarfs, the monsters may try to destroy the these blocks, making the structure fall as an item to be gathered. To avoid this, place the soul keeper on bridges (of any kind), as they're not targeted by monsters.

Removal
It may be removed without being destroyed.

If it is removed with dwarf souls inside, the souls will be lost. If there are no souls inside it, the soul keeper may be rearranged with no fear.

Use
When a dwarf dies and the player hasn't any soul keeper placed, this dwarf is gone for good. However, if there is an already placed soul keeper, the dwarf's soul flows into this structure. Now, the player has 3 options:
 * Ressurect the dead dwarf using a Potion of Resurrection — the same dwarf will respawn at the stockpile;
 * Dismiss the dwarf's soul — his/her soul will leave, and a new random dwarf will spawn normally, as though there was no soul keeper;
 * Let the soul waiting inside the soul keeper — in this case the population won't regrow.


 * The third one may be a good option if the player has no dragon eggs to craft potions of resurrection. If the dead dwarf is a useful one, with a considarable skill development, it may be fair to endure the low population cap until all ingredients are obtained, and the player be able to resurrect the dwarf.
