Empathy is also a psi ability that comes in two "flavors:" clairempathy and
telempathy. One, is the ability to sense and feel what other people are feeling,
while the other is the ability to communicate with animals. There's also psi-
induced charisma, an unique aspect of empathy, and lastly related to empathy
is the gift of telesthesia: the ability to project one's emotions on to someone
else (whether they want them or not).
While it's not a fun ability to have, it's a very useful and sometimes formidable
ability. An empath knows when someone is lying, or can sense bad psychic
environments and alien, or ghostly influences. There's infinitely more to empathy
than that silly dictionary definition.
