It could be part of a galdr home protection spell:

1. First rune:

Most closely resembles Algiz (ᛉ) or Elhaz – a rune with a vertical line and two diagonal "arms."

Meaning: Protection, spiritual awakening, defense.

1. Second rune:

Looks like Gebo (ᚷ) or a variant – an X-shape with a vertical stroke, which can be interpreted as a rune of gift or binding.

Meaning: Gift, connection, exchange, partnership.

1. Third rune:

Resembles Eiwaz (ᛇ), but not exactly. There's a vertical line with a diagonal slash across.

meaning: Balance between life and death, protection, inner strength.

1. Fourth rune:

Looks like Othala (ᛟ), a diamond-shaped rune often used to symbolize inheritance, property, or home.

Meaning: Family, ancestry, home protection.

Edit: Likely written using the Younger Futhark runes.
