Mjölnir

Mjölnir (pron.: MYOL-n(ee)r; also Mjǫlnir, Mjollnir, jölner or Mjølner) is the hammer of Thor, the Norse god of thunder.

Lara Croft' sought the hammer in Tomb Raider: Underworld''. '''

History
Thor weirded Mjölnir in many battles harnessing, weilding it's massive power, making him a deadly warrior,. Despite this, Thor eventually fell in Battle.

Odin separated the hammer from Thor's gauntlets and belt which allowed him to wield it, placing them within treacherous temples that would stop anyone who was unworthy of wielding Mjölnir from obtaining it.

Centuries later, Natla, who sought to begin the seventh age, employed Richard Croft to find the Mjolnir. Croft found one of Thor's Gauntlet's in a temple in Thailand, however, having discovered Natla's intentions, Croft, destroyed the map which revealed the locations of the other pieces, and hid the gauntlet in the catacombs of Croft Manor in a hidden office, along with a copy of the map for his daughter Lara.

Natla later tried to force Croft to reveal the locations of the other pieces, however he refused leading her to kill him.

Some time later, after another failed attempt to start the Seventh Age. Natla was discovered and captured by Amanda Evert. Amanda was seeking a way to reach Avalon (which was also the Norse underworld Niflheim) which Natla saw as her opportunity to once again try and locate Mjölnir and gain access to Helheim, and helped her.

Amanda knowing that Lara Croft was also seeking a way to Avalon, followed her to the Mediterranean, where she discovered Thor's gauntlet. Amanda's mercenaries stole the gauntlet from Lara, however, Lara had already put the Gauntlet on, which meant that it would be bonded to her until her death.

Lara made her way onto the ship where Amanda was keeping the gauntlet, and met with Natla who told her of the link to Helheim and her mother's disappearance, in order to give Lara the drive to find the other pieces. The ship began to sink, due to damage caused by an explosion that resulted from a botched attempting to kill Lara.

Ass the ship went down, Lara saw Amanda, who returned the gauntlet, allowing Lara to do the hard work in retrieving Mjölnir.

Mythology
Though generally recognized and depicted as a hammer, Mjölnir is actually an axe or club but misconceived as a hammer. In the 13th century Prose Edda, Snorri Sturluson relates that the Svartálfar Sindri, the brother of Brokkr, made Mjölnir while in a contest with Loki to see who could make the most wonderful and useful items for the Gods and Goddesses in Asgard
