Dear Brothers Mine (джен)

Asgard had not one but two Golden Princes: the well-loved crown prince Thor and the equally if not more adored and protected Balder. That left Loki with little space to shine. Well, he gave up hoping at all when the Norns’ prophecy arrived the day Balder was born, when Odin ordered Frigga to cast a protection spell for Balder against all harms, when his mother wordlessly obliged.
Until, that was, when he became the only one between the mead of mistletoe from the Frost Giantess he invited into Asgard himself to stop Thor’s coronation, and his youngest brother was so eager to down his first drink.
Right after he learnt that Balder and Thor weren’t even his brothers.
