Bats lend added protection to the stronghold of the morroval-inhabitants of Dannenglor.
'I am glad that you have come to our aid, my good ${RACE}. As our path leads us through Mirkwood, we see many evil things which we wish to make right. Alas that we have not the resources for such a great undertaking. Even the smallest good deeds must often go undone, for our eyes are fixed upon one target only.
'Dannenglor was once an Elven-home and is overrun now by shrieking beasts of all kinds. The merrevail and mervyl are violations of nature, and even the bats of this forest are unwholesome and evil.
'If you wish to make Mirkwood a little better on behalf of the Galadhrim who must pass through it, you should cleanse those ruins of the vile swarms of bats that give strength to the presence of the merrevail. Will you do this for us? Dannenglor will never be fair again, but you can perhaps begin to cast the evil from within its walls.'
Ruins-bats can be found in the ruined Elf-stronghold of Dannenglor, north of the Haunted Inn in the Dourstocks.
Mírdiniel has asked you to defeat several bats in Dannenglor when you venture next into the wilds of the Dourstocks.
Mírdiniel is at the Haunted Inn in the Dourstocks of Mirkwood, south of Dannenglor.
You should speak with Mírdiniel and tell her of your efforts in dealing with the problem of bat-swarms in the woods.
