Strider, worried for his wounded friend, has asked you to seek a herb called \qKingsfoil,\q which he believes will slow the poison of the evil knife that pierced Amdir.
'Amdir, my poor old friend! A shadow has crept over him... the Black Rider that stabbed him is more fell than any creature you will meet in your travels!
'We have little time, and we must stretch what time we have by doing two things at once. Amdir needs medicine, ${PLAYER}, and quickly. Do you know of a plant called kingsfoil? It has great power to heal.
'You should ask Captain Brackenbrook if he knows of any that grows in these parts. Offer him assistance as well, if it does not take you far out of the way. We must begin to work on him, and perhaps he will look more kindly upon you after you do him a good deed.'
Captain Brackenbrook is near The Mad Badger Inn in the village of Archet.
You should ask the Captain if he knows of any kingsfoil plants nearby and also if he would like some assistance to earn his favour.
Calder Cob is at a farm outside of Archet, on the way to Bronwe's Folly as you take the road south from the town. Kingsfoil can be found at Bronwe's Folly.
You should speak with Calder Cob and see how you can assist him against the threat of attacking wolves before heading to the ruins to pick kingsfoil.
Strider is in the town of Archet, awaiting your return with leaves and news of your efforts to get Brackenbrook to trust you.
You should bring Strider the kingsfoil and inform him of Calder Cob's treacherous behaviour.
