Yes, Frostmourne hungers for souls.
NO!!!! you can't Frostmourne stay's with arthas permanently
The Lich King's weapon is called Frostmourne.
Frostmourne
The Frostmourne sword comes from the video game World Of Warcraft. World of Warcraft was released in late November of 2004 in North America and Australia.
The Japanese word for "Frost" is 霜 (しも) - shimo; Mourne is 悔やむ - Kuyamu. The latter is a verb. If you would combine these literally, Frostmourne would be "Shimokuyami" I think. If you simply translate Frostmourne phonetically, saying "Furosutumon", it would be written as フロストモ-ン. Note that the last "mon" is a long vowel, pronounced as " mown" in English.
No, Frostmourne is not a player equipable weapon. It is Arthas' sword. No one else can use it.
No. Blizzard has said that Frostmourne is 'soulbound' to Arthas and will not drop from him, ever.
Frostmourne is not available as a weapon in World of Warcraft without being on a private server, where a fascimile might be spawner. Shadowmourne, the legendary player equivalent for Death Knights, Warriors and Paladins, is obtainable through a long questline starting in Icecrown Citadel on 25man. This quest first requires obtaining the shaft of Arthas' old mace (to be picked up in the icy cave where Frostmourne was first discovered) and a number of Orbs (obtained with Justice points or dropping from ICC bosses). The starter quest is available directly after zoning into ICC, from an NPC nearby. After that, you must perform various other tasks including killing a number of bosses, performing special feats during boss fights (like getting breathed on by Sindragosa) to charge the weapon. It will become increasingly more powerful until the final step - defeating the Lich King. Once this is done you will have the legendary weapon Frostmourne. Finding this weapon on WoWHead or WoWpaedia will also link through to the entire questline required to get it.

The Hunger Games
There are five different types of hunger. They are mind hunger, taste hunger, habit hunger, stomach hunger, and body hunger. These can all be controlled with practice to keep people from consuming more than they need.
