The easiest way to find North is by using a compass:

Simply rotate your character until the arrow is pointing toward the letter C (Russian: Север, romanized: Sever, English: North).

Below is a translation of all four directions on the compass:

C - North (Russian: Север, romanized: Sever)
Ю - South (Russian: Юг, romanized: Yug)
В - East (Russian: Восток, romanized: Vostok)
З - West (Russian: Запад, romanized: Zapad)
