In the land of Dragonia five various inhabitants were having a very bad week. Each of the five inhabitants had fallen out with two of the others, but on different days of the same week. The week starts on a Sunday. One of the inhabitants, a different one each time, stepped in to try and resolve these disputes with little success.

Who fell out with whom, on what day and who tried to help resolve matters?

Days: Sunday, Tuesday, Wednesday, Thursday, Friday.

The Unicorn's second dispute of the week, surrounding ownership of a piece of worthless land, was not on a Friday.

The Dragon tried, unsuccessfully, to resolve a dispute the day after the Elf tried to solve one concerning doing washing up at the local community centre.

The Pixie did not try to resolve a dispute on a Sunday.

The Unicorn never had a disagreement on a Tuesday or Thursday, but he did try to resolve a dispute on one of these days. He never tried to resolve a dispute involving the Dragon.

The Elf's second dispute of the week was the day after the Pixie's second dispute of the week. The Dragon's first dispute of the week was the day before the Pixie's second dispute of the week.

The Pixie never fell out with the Elf, however the Elf did try to resolve one of the Pixie's disputes, which was later in the week than the Elf's dispute which the Fairy tried to resolve.
