Greater Fist of Heaven
The formerly dormant volcano known as the Greater Fist lies within the southern border of Therengia. This terrible example of the raw power of nature recently erupted, destroying the halfling settlement of Sicle Grove. Travelers should avoid the area if possible.
Description from Pentaith at The Wren's Nest
The second volcano in Zoluren. Larger, and more active then the Lesser Fist. Mibgluc's stronghold was atop the Greater Fist of Heaven, and he used it to destroy Sicle Grove. The Greater Fist of Heaven is now accessible through the ruins of Sicle Grove. Darkstone was also destroyed by the rage of the volcano. The path up the volcano is treacherous, and few will know to help if you fall to your doom from the dangerous footpaths.
