Etymology: For eruptive pseudopodia. From Quenya Orodruin (“fiery-mountain” ( Fauskanger 2008); Mount Doom) the older and most common name of the volcano in Mordor, in which Sauron forged the One Ring. Orodruin seems to respond on the level of Sauron’s powers and whether he is in Mordor and change its eruptive activity ( Tolkien 1954) resembling a living thing.

Grammatical gender is feminine.
