Arkhelthingril Arkhelthingril ( also known as Ice ) was an old female white dragon who was transformed into a dracolich by the archmage of Maerimydra , Duneth Wharreil . Description . About 20 - ft - long ( 6 m ) , Ice ' s form had not fared well since its transformation into a dracolich and her flesh had rotted to the point where her bones were visible . Personality . Arkhelthingril was a manipulative and patient example of her kind . When dealing with others she was coldly calculating and would often try to seek to bargain something out of them , trading information and even her co - operation depending on the prize offered . She had the same avarice as other dragon s and was even willing to subject herself to the dangerous experiments of Duneth Wharreil in order to acquire great wealth . Despite being transformed into a dracolich , she was a cautious creature , and preferred to observe and avoid her foes until she was sure she could overwhelm them . She would even take time to administer coup de grace ' s on her foes , if she could . Abilities . As a white dragon of some age , Arkhelthingril could expel a 50 - ft ( 15 . 2 m ) broad cone of cold upon her foes and was able to manifest a cloud of freezing fog . Upon her transformation into a dracolich , Ice gained considerable powers . She could paralyze foes with but a glare or touch and was able to reform even after defeat , thanks to her phylactery . Possessions . Despite Arkhelthingril ' s agreement for treasure with the archmage of Maerimydra , after her transformation into a dracolich she was still without a single coin . Even her phylactery — a large , flawless pearl — was held in ransom by Duneth to keep her obedient . The pearl alone was worth 2 , 600 gp , even before considering its status as a powerfully enchanted item . Relationships . Ice had a checkered relationship with Duneth Wharreil , the archmage of Maerimydra . For a time , they had an agreement of mutual benefit where Duneth would provide the dragon with great wealth . However after Arkhelthingril ' s transformation into a dracolich , Duneth reneged on the agreement and used her phylactery as a means of keeping Ice compliant . History . Early Life . Arkhelthingril was born at some point between 972 DR and 1171 DR . Although Ice shared the same draconic lust for treasure as the rest of her kind , eventually she became desperate enough for more wealth that she was willing put her life on the line to negotiate with the drow of Maerimydra . Silence of Lolth . In 1372 DR , Irae T ' sarran raised the Undying Temple in Maerimydra and transformed the archmage of Maerimydra into a silverwraith in the wake of Lolth ' s Silence . As the Undying Temple began to disrupt the " Weave " around it , the silverwraith Duneth Wharreil started experimenting with the corrupted magic from the temple in Castle Maerimydra . Duneth set his sights on creating a dracolich and despite at least one failed attempt with a black dragon , the archmage managed to persuade the white dragon Arkhelthingril ( also known as ' Ice ' ) , to become a subject . To this end , Duneth promised Ice a vast amount of wealth in exchange for her cooperation in the process . Together they were able to bind the white dragon ' s life force to an enormous pearl , successfully transforming her into a powerful dracolich . However , after the completion of the ritual , Duneth left Ice ensconced in the former banquet hall of House Chûmavh and placated the undead dragon with promises of future treasure . To add weight to his promises , Duneth kept hold of Ice ' s phylactery to ensure the dracolich ' s dwindling obedience . By 1374 DR , Ice still resided in Maerimydra .
