Abadon, s podnaslovom Bajka za starce, je antiutopični satirični roman Nejaza Nemcigrena (anagram Janeza Mencingerja). Prvič je bil objavljen leta 1893 v Ljubljanskem zvonu, kjer je izhajal periodično skozi celoten letnik.
This is the best, best, best novel I have ever read. The message is very inspirational and we learn a lot about life. We learn that all we want are material things but we often forget about our soul's wealth. The way of explaining the morality is very Catholic (God and Devil that both strive to guide a person's life), but still applyable for any other way of thinking. The books made me ponder about life and morality, about we are looking for and about what we really need to live a decent life.
