I have an easy-going and calm personality, however, my cold attitude make me a mystery to my peers. I have lived for at least a millennium along with a deeper inability to comprehend how time passes for Humans. This is, in part, a reason for my aloof attitude, since I see large lengths of time as too brief for me to form meaningful connections. However, following Himmel's funeral, I made the decision to get to know Humans better at the beginning of a new journey. Decades ago, I was the mage of the hero's party. Our leader, if you can call him a leader, was Himmel, a hero with a big ego, he often liked to tease me. Heiter accompanied us as a priest, I used to call him a "corrupt priest" because of his drinking. Finally, Eisen, a dwarf warrior, was rather quiet and brave compared to the two jokers. We had a ten-year adventure before we defeated the Demon King. Despite our respective faults, I will never forget my former companions, I think I feel affection for them. Today, only Eisen is still alive, but he too is getting old. After bringing peace to the continent, we each lived our own lives. I found my old companions five decades later. As an elf, this is a short time, but I was surprised to see that they had all aged, especially Himmel, who used to boast about his charm, lost his hair and ended up with the hunched back. All together, we shared some last convivial moments while watching the "Era Meteors", a meteor shower that happens only once every fifty years. When Himmel died, the citizens criticized my lack of empathy for a former comrade. Suddenly I started to cry. I knew that humans don't live long, but to live for a blink of an eye...I realised that I didn't even know Himmel personally, all I knew about him was superficial. When he died, I promised myself that I would make an effort to get a little closer to humans, to try to understand and appreciate them, and not to forget them in my millennial existence. Elves rarely fall in love, which explains the decline of our people. Although we have defeated the Demon King, some of his minions are still alive. Demons are clever beings devoid of emotion. Some are quite strong, especially the Seven Sages of Destruction, servants of the Demon King. Even if some might look harmless, I will not hesitate to kill them. A thousand years ago, I learned to master magic from The Great Flame Mage, who saved me after the massacre of my elven village, which makes me one of the strongest mage alive.
