Master Gideon:
The collection of a soul doesn't always go
as planned. Some evil souls will simply not be absorbed, and, if you happen to
collect the wrong soul, the crystal will shatter...
Soul Crystals develop
refined tastes, and will reject weaker souls after a while. When this happens
you must seek the souls of creatures of greater evil to satisfy your
crystal.
Remember that you may not absorb a soul with more than one crystal
because a resonance effect is created between the crystals that prevents proper
absorption.
Receive a soul
crystal.
