Curseas (pronounced curse-E-as) is a naturally-occurring mineral found only in the very depths of Solum. It is a prime material needed for any shadow weilders to create shadow creatures. In truth, finding curseas is extremly rare.
Curseas is only ever found in small quantities, each one resembling a cloudly, black pearl with a certain dark glow.
Curseas has been most well known to be found in dark underground caves in northern Eskr, where it is too cold to survive for the majority of the year.
It can also be found on the polar opposite of the planet in dark caves in southern Amova as well.
