Rune Eye

A Rune Eye (ルーンの瞳) is a mark held by the members of Team Ragnarok as proof of being the wielders of the Three Polar Gods.

Firstly seen on 118, when Dragan summoned Polar God King Thor, a "Thorn" Rune formed and glowed on his left eye.

History
Harald was the first seen to obtain the Rune eye. While flying along with another comrade on a military plane, suddenly a burst of light occurred followed by mysterious appearance of a storm. While on the storm unable to see anything, Harald's rune eye appeared and with its power allowed him to see through the storm and prevent crashing on mountain. Long after this event, Harald found Odin's card on a treeroot. The rune on his eye is a "Ash" symbol, meaning "One of the Æsir (gods)".

Dragan obtained its Thorn rune after obtaining Thor's card, though he didn't keep or used the card then. While climbing an avalanche came down, still the Thorn rune protected him and after this Harald convinced him to use Thor. The rune on his eye is a "Thorn" symbol, meaning "the god Thor".

Brave being the last one to obtain such rune after stealing Loki's card. While trying to escape with the card, his boat crashed against a boulder and send him flying to a pillar of rock and almost crashes. However the final rune eye appeared on his eye and a thunderbolt appeared from the sky to destroy the pillar. The rune on his eye resembles the "Hail" symbol, also meaning hail (the precipitation).

Behavior
The Rune Eye shares many similarities with the Crimson Dragon's birthmark.

It allows Harald, Dragan and Brave to use the power of the Polar Gods, as well as represent a connection with this cards and to each of themselves respectively. It protects them from any danger or threat.
