Fortunately, Unfortunately

[Jubal]

Fortunately, she may yet become the protagonist of a bestselling novel

[Caradìlis]

Unfortunately, she has her moment of glory stolen by another mouse-like character in a different bestselling novel...

[Jubal]

Fortunately, a titmouse is a kind of bird, not a kind of mouse

[Caradìlis]

Unfortunately, this witch does not google things before she opens her mouth, which ends in many a mishap that eventually lead to WWIV (not claiming ownership over WWIII, pretty sure the Americans will take care of that one before I get there...)

[Jubal]

Fortunately, as the old adage says, WWIV will be fought with sticks and stones, and as another adage says, those can break bones but are usually non-fatal, so the whole thing is fairly anticlimactic.

[Caradìlis]

Unfortunately, I now have a very terrible song stuck in my head and can no longer be productive at anything, thanks.

[Jubal]

Fortunately, this means you can't produce WWIV

[Caradìlis]

Unfortunately, my plans of preventing WWIII from happening, have also been thwarted...

[Jubal]

Fortunately, WWIII is stopped anyway when everyone discovers a new purpose, a new goal in life. A new source of worship, wisdom, and power.

Is it a deity? Is it a great leader? Is it the Mighty Mushroom of Mundifron?

If you guessed c you were right, it is absolutely the Mighty Mushroom of Mundifron.

[Caradìlis]

Unfortunately,  the Mighty Mushroom of Mundifron is only interested in bringing about the apocalypse, so that's not very helpful...

[Jubal]

Fortunately that's a mistranslation in the Holy Spore Book of Mundifron. The mushroom is actually interested in bringing about the alpacalypse, which is much fluffier.

[Caradìlis]

Unfortunately, dying of fluff is still dying

[Jubal]

Fortunately, biospheres containing earth's species and life get to escape the alpaca takeover, piloted deep into space.

[Caradìlis]

Unfortunately, now space is contaminated with the worst disease imaginable: humanity...

[Tusky]

This thread almost inevitably ends up with an apocalypse, or how humanity is fundamentally doomed... whilst that is depressing and perhaps true, it's a fairly boring thing to follow on from.

Fortunately Tusky does so anyway, by using randomness.  The Mighty Mushroom of Mundifron releases a tabloid newspaper column called "all my spores".
