I'm curious. Suppose I were to be deprived of technology and had to

Earth's axis is inclined at an angle instead of being perpendicular?

Apart from the absence of seasons, if the earth's axis was
perpendicular to the ecliptic, the angle between the sun and the pole
star (assuming there was one) would always be 90 degrees.
